Pengaruh Ekstrak Kulit Buah Naga Merah (Hylocereus Polyrhizus) terhadap Waktu Perdarahan (Bleeding Time) Pada Mencit Strain Balb-C

Tooth extraction causes prolonged bleeding complications and the body will respond with hemostasis. Currently developing natural medicines to help the process of hemostasis. Red dragon fruit peel, which is generally a waste containing tannins, flavonoids, and saponins to stop bleeding. Purpose was to find out the effect of red dragon fruit peel extract on bleeding time in the tail of Balb-C strain mice. 16 mice samples were adapted for one week. Mice were divided into 2 groups subsquently fasted for 7 hours. The first group as a control (0.5% Na-CMC). The second group was given red dragon fruit peel extract which was divided into three sub-groups at a dose of 0.5 mg / g BW, mg / g BW, and 1.5 mg / g BW. All samples were waited for 45 minutes and cut along 2 cm from the tip of the tail. Blood is spilled on Whatman paper which has 30 seconds in each box. The number of blood spots on the box was calculated and multiplied by 30 seconds. The result showed that bleeding time in the group given red dragon fruit peel extract was significantly lower (p <0.05) than in the control group. The conclusion was red dragon fruit peel extract (Hylocereus Polyrhizus) has an effect on shortening the bleeding time in cutting the tail of bulb-c strain mice and the dose of red dragon fruit peel extract (Hylocereus Polyrhizus) which has the most significant effect is 1 mg / BB mice.

Effects of red dragon fruit peel extract on tomato storage

The aim of this study was to identify the effects of the peel extract of red dragon fruit on the quality of tomato fruit during storage. Twenty one tomato fruits were immerced in the peel extract with concentrations of 0% (T0), 25% (T1), 50% (T2) and 100% (T3), where T0 to T3 represented the various treatment groups. Three fruits in each treatment were then randomly selected every two days, for quality analysis.

Furthermore, there was no significant difference in the total soluble solids, and this indicates that the extract had no effect on fruit sweetness. Interestingly, fruits from T3 did not show any damage caused by fungus. In conclusion, the extract of red dragon fruit peel has antioxidant potential, which can be useful for food storage.

Antioxidant and Anti-Hyaluronidase Activities of Dragon Fruit Peel Extract and Kaempferol-3-O-Rutinoside

Aging is a natural process in human life and is triggered by the presence of free radicals (ROS). The use of antioxidants from natural ingredients is one of the breakthroughs to overcome aging and counteract the harmful effects caused by the free radicals. This study aimed to determine and compare the antioxidant activity of H2O2 scavenging and hyaluronidase inhibition of red dragon fruit peel extract (DFPE) and kaempferol-3-o-rutinoside (KOR) compounds. Dragon fruit peel extract (DFPE) is obtained through extraction by maceration method using 70% ethanol solvent. The design of this study included antioxidant and anti-aging activity assay of EKBN and KOR at the series concentration of 15.63; 31.25; 62.50; 125; 250; 500 µg/mL through H2O2 scavenging, as well as the DFPE and KOR hyaluronidase inhibition assay at the series concentration of 5.21; 10.42; 20.83; 41.7; 83.33; 166.67 µg/mL. EKBN shows that the average activity of H2O2 scavenging is lower than KOR. In addition, the IC50 values of KOR for H2O2 scavenging is lower (351.46±2.30ug/mL) than DFPE (409.64±23.17ug/mL). While, KOR also has higher values of inhibitory activity than of the DFPE. However, the IC50 value of KOR for hyaluronidase inhibition activity was 84.07±10.46µg/mL, equivalent to the IC50 value of DFPE (85.32±10.24µg/mL). The presence of antioxidant and anti-aging activity in the EKBN is probably caused by betalain and the KOR compound itself contained in red dragon fruit. The results of the paired-samples T-test on antioxidant activity and anti-aging of DFPE and KOR showed non-significant difference. Thus, DFPE has an equivalent antioxidant and anti-aging through H2O2 scavenging and hyaluronidase activity as possessed by the KOR compound.
